A nurse in an emergency department is reviewing a client's ECG reading.

Which of the following findings should the nurse identify as an indication that the client has first-degree heart block?

Prolonged PR intervals.

Nondiscernible P waves.

More P waves than QRS complexes.

No correlation between P and QRS waves.

Answer and Explanation

The Correct Answer is A

First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.

Correct Answer is B

Explanation

The priority intervention for a nurse planning care for a client who has status epilepticus is to administer diazepam intravenously to the client.
Diazepam is a benzodiazepine medication that can help stop seizure activity and is often used as a first-line treatment for status epilepticus.
Choice A is incorrect because while phenytoin can be used to treat seizures, it is not typically used as a first-line treatment for status epilepticus.
Choice C is incorrect because while providing oxygen can be an important intervention for clients experiencing seizures, it is not the priority intervention.
Choice D is incorrect because while turning the client to the lateral position during seizure activity can help prevent aspiration, it is not the priority intervention.

A. Place pillows under the client's knee. B. Perform range-of-motion exercises on the client's knee. C. Apply an ice pack to the client's knee. D. Gently massage the area around the client's incision.

Correct Answer is C

Explanation

Applying an ice pack can help reduce pain and swelling after total knee arthroplasty.
Placing pillows under the client’s knee (choice A) is not recommended as it can hinder circulation and delay healing.
Performing range-of-motion exercises to the client’s knee (choice B) may be part of the rehabilitation process but should be done under the guidance of a physical therapist and may not be appropriate for immediate pain relief.
Gently massaging the area around the client’s incision (choice D) may not be appropriate as it can cause discomfort and disrupt the healing process.
